Solar Flares and Coronal Mass Ejections

Solar flares and coronal mass ejections (CMEs) are powerful explosions that can disrupt Earth's magnetosphere and cause geomagnetic storms. The animation on this page demonstrates how CMEs can expand into space.

A four-part eruption occurred at around 10:00 AM EDT on Tuesday, April 23, as captured by NASA's Solar Dynamics Observatory (SDO).
